We loved staying at Nui's place in Phra Khanong. It was very convenient to be within walking distance to BTS. The rooftop pool was nice to have. Wifi worked great. Nui was very hospitable and gave us a map of the city with suggestions of what to do and some scams to watch out for. Our plane didn't land until 11pm but late check-in was not a problem. You have to go for Thai massage on the corner. 200 baht/hr. So good.
